- Use some obstacles (Such as walls).

2. The repeater’s power is on but the phone cannot get connected to the network and still can not

communicate.

Reason 1:

There are loose or wrong connections in the repeater system.

Solution:

Please try to fasten the connections between different parts of the system.

Reason 2:

The signals received by outdoor antenna of other operators nearby are too strong. (For example,

the other operators’ signals are 10 dB stronger than the needed signals.)

Solution 1:

Change the direction of the outdoor antenna or its installation position, so that the gap of signal

strength is reduced between operators.

Solution 2:

Use barriers (like buildings and walls) to block signals from other operators.
